Reed afterwards accompanied Gen. Eaton's detachment to the coast of Africa, and served on board the vessel which co-operated with him on that romantic expedition.

When war was declared against England last summer Capt. Reed solicited employment, though his health was extremely delicate. He was ordered to a command to the southward, whither be repaired immediately notwithstanding the unhealthiness of the climate at that season. The death of Capt. Gadsden preferred him to the command of the brig Vixen. The sea air, in a great degree restored his health: but it was his peculiar hard fate to be captured by a force so superior as to preclude any contest, (the Southampton frigate) then to be shipwrecked on an inhospitable coast, and finally to die a prisoner among strangers. During all these reverses, however, he preserved that equanimity and resolution which never forsook him. When the Southampton and Vixen ran ashore, in the night, the English crew became mutinous from intoxication, and what was saved from the wrecks was principally due to the exertions of the American seamen, under the direction and encou. ragement of Capt. Reed. For this generous interposition he received the public acknowledgments of Sir James Yeo, the British commander, and an offer of his
